CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 409,219, dated August 20, 1889.

Application led September '7, 1888. Serial No. 284,809. (No model.)

To all whom it may concern:

Be it known that I, WAITMAN M. MORGAN, a citizen of the United States, residing at Kansas City, in the county of Jacksonand State of Missouri, have invented certain new and useful Improvements in Oar-IVheels; and I do hereby declarethatthe following is a full, clear, and exact description of the same, which will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying' drawings, forming a part of this speciiication.

My invention has for its object, iirst, to enable the vibrating of traction-wheels of a car, in describing the curves in a track, to be governed in advance between two traction-points on each curved-track rail; second, to permit the advanced and retreated trailers to ac-` commodate themselves to the inequalities of the track.

In the drawings, Figure lis a side elevation of the car-wheel shown upon its track, and with its axle journaledwithin the journal-box, attached to the outer side-supportingbeamof the truck-frame or floor-beam of a car, and the radial arms on the cylinder pivoted ad j u stably to said beam and carrying the advanced and retreated rollers and brake. Fig. 2 is a vertical sectional view taken through the wheel and bearing of the cartruck and track at right angles to and upon the, line Fig. l, showing in illustration in dotted lines the relative position of the axle when the wheel vibrates thereon. Fig. 3 is a detail sectional view of the axle-bearings, taken at right angles to and upon the line 'y y, Fig. 2, showing the registering grooves in the globular hub and opposite central bearing of the wheel and the interlocking-balls thereon. Fig. a is a detail sectional view of the peripheral end portion of the wheel, as shown in Fig. 2. Fig. 5 is a detail section al view, partly in plan and partly in horizontal section, of the yielding end portion of the radial arms, showing spring-held roller. Fig. 6 is a plan view of a section of curved track, showing the relative position of the traction and trailing rollers in describing a curve.

Like letters of reference indicate corresponding parts in all the figures.

In carrying out my invention, A represents the horizontal side beam of the truck-frame or floor of a car. B is the track-rail. C is the vibrating traction-wheel, and D its axle. In the construction of the wheel `C two circular side disks c c are formed, the diameters of which are equal and proportionate to the circumference of the wheels. From one or the relative inner side portions of each disk c c', extending from the line of the axis of said disks radially the distance required for the axle-bearings and equal in width, are cast rigidly on said disks the circular flanges c2 c2, which portions c2 c2 are connected with the disks c c firmly together by the transverse bolt c3, which passes through said flanges and said disks as far radially from the point of the axis of said disks as is practicable. In a transverse relation to disks c c and through the axis of said disks and the flanges c2 c2 is iirst made a circular opening c4, exceeding in proportions the proper degree to that of the diameter of the axle D. In the sides of said opening c4, and concentric thereto, is made a groove c5, which extends in a transverse curved relation to the side' disks c c from one outer side portion disk c to an outerside port-ion of the opposite disk c and at equal distances apart circuniferentiallyin the groove c5. Extending below said groove into the iiange portions 02 c2 of the side disks c c are made the concentric depressions ci c6, which extend in a transverse relation to a point in a vertical opposite sides c c', the ends of said grooves inclining in opposite directions and describing a line in relation to the axis of the wheel.

In the concentric grooved depressione5 of the wheel O is placed a solid globular hub or ball CZ, which is made of the proper size dithe laterally ametrically to iit within the dimensions of said opening, so as to turn freely. Through the ball d in the direction of its diameter, and in the direction of the line of the axis of said disks c c', is made a circular opening d', through which opening is inserted the axle D. Said ball d is then keyed upon or otherwise rigidly attached to the axle D.

In the ball d, and extending below its surface, are made at suitable distances apart registering with the concentric grooves c6, the concentric depressions d2 d2, which. are equal in depth to the said depression c6 and in length extend to the opposite points in aline line relatively with the inner portions of the IOO radially with the ends of the grooves cG on the wheel C. In each of the said registering depressions c6 d2 is placed a small looselyfitting globular block cl3, one-half of block cl3 extending below the surface of the ball d. Between the opposite side disks c c of the wheel C, near the peripheral portions of said plates, and of a thickness ,equal to that of the combined flanges c2 o2 on said disks c c and forming the circular tread of the wheel C, is placed a concentric fiat ring c7, the outer circumferential portion e8 of which ring extends radially to a point a short distance from the peripheral flanged portions 09 c9 of saidwheel C. The inner circular portions of the ring c7 extend radially toward the flanges c2 c2 comparatively one-third of the relative distance from said portions e8 to said flanges c2 c2, and between the disks c c and the flanges c2 c2 and ring c7 is formed an annular chamber cx. For the purpose of retaining the ring c7 inA placelb-etween the side disks c c a circular flange c10 is cast upon the inner side portions of the plates c c in chamber cx, which is in close contact with the inner side portion of and forms a bearing for said ring.

In the inner side portions of the disks c c', opposite the ring c7, at suitable distances apart and in opposite relations to each other in the line of the circumference of the wheel C, are made the concave recesses 010 010, which extend through the outer sides of said disks c c', forming a concentric opening cn. In a transverse relation to the sides c c of the Wheel C, and through the ring cT opposite the concave recesses 010 010, are made the slots cl2. In the ring c7, extending from the tread o8 in a line radially to the axis of the wheel through slot c12 and at a point centrally between the opposite side disks c c', is made a perforation cl3, which is screw-threaded a suitable distance. In said perforation c13 is inserted a threaded pin c, and upon said pin in the transverse slot c12 is loosely mounted an antifriction roller C15. In each of the concave recesses 010 010 is then placed a small ball c1, which projects outwardly a short distance beyond the outer side portions of the disks c c.

Extending laterally a short distance from the outer sides of the disks c c', in a curved plane equal in extent to that described by the concentric curved depression c5 and in a circular relation around shaft D, are cylinders E E ,upon the extreme outer ends of which cylinders are the radial flanges e c. Upon cylinder E is loosely mounted a circular flat disk F, which is relatively one-third the dimensions of the wheel C, and is provided with a central opening fo, adapted to receive said cylinder E, and upon the cylinder E', on the opposite side of the wheel C, is mounted in a similar manner a disk F', provided with a like transverse central opening. From the peripheral edge portion of the circular disks F F extend, in a transverse relation to a point in line with the under side portion of the fioor-beam A of the car, the radial arms f f and extending from the upper end of one to the upper end of an opposite arm f in a horizontal relation is a plate f2.

Attached rigidly to and extending above the plate f2 at a point an equal distance from the opposite arms f f is a pivot f3. Through the beam A in truck-frame of a car, at a point intermediate between the opposite sides, is made a square opening a2 of a suitable size. In said opening a2 is placed a movable block a3, smaller in dimensions than the said opening a2. In atransverse relation to said beam A and the opening a2 from one side of said beam is made a screw-threaded perforation a4, and in said perforation is fitted an adjusting-screw a5, the end of which in the opening o,2 bears against one side of block a3. Upon the opposite side of the beam is made a similar screw-threaded perforation a6, in which is an adjusting-screw a7, which bears against an opposite side of the block a3 to that receiving the screw a5. In the lower side portion of the block a3 is made a vertical perforation a8, in which is inserted the pivot f3 on the plate f2 of the radial arms ff. On the outer side portion of the beam A is attached the upper end portion of a journalhanger G, the lower end portion of which carries a j ournal-box g, in which is journaled one end of the shaft D. From the opposite circular side disks ff on the wheel C, and radially from the axis of said wheel and the peripheral edge portion of the said disk in one direction toward the track B, extend the arms f4 f4, and extending in a similar relation to the disks F F toward the track D, in an opposite direction to the arms f4 f4, are the arms f5 f5.

From the ends f4f4f5f5, in a transverse relation and extending back a short distance toward the axis of the wheel, is removed a lower rectangular portion, leaving a narrow projecting end f6, the extreme end of which f X f is made nearly flat.

To the inner side, and at a point toward the axis of the wheel a short distance from the narrow portion f6 f6 f7 f7 of the arms f4 f4 f5 f5, is pivotally attached by the pivots f8 f8 f9 ff to each respective arm a short extension f 10 flo f11 f, which extends an equal distance and nearlyto the track B. Through the extreme ends of the extensions flo flo f11 f of the arms is extended in a transverse relation the rod f12 fm. Upon each respective rod are mounted loosely the small flanged trailerwheels f 13. Upon the rods fw, on opposite sides of the flanged wheel f 13, are placed the spiral springs f f1", which bear against the sides of the wheel f13 in one direction and in opposite directions against the sides of the extensions f1@ flo f11 fu. Upon the outersides of the extensions f10 f10 f f, on the lower' edge portion, beneath the flattened end portion fxfx of the radial arms fA1 f5, extends laterally the flange flf", upon which is suitaroo I IIO bly secured the lower end of a spiral spring f1, and upon the upper end portion of which the flattened end portion fx1 X of the radial arms f4 f5 is permitted to rest.

For the purpose of arresting the wheel two radial arms f17 fr the peripheral edge portion of the circular plates FF in an upward direction toward the end of the platform of the car and a short distance above the wheel C. To and between said upper ends of said arms is pivotally attached the short end 7L of a lever H. Upon said short end 7L of said lever ll is pivotally attached a brake-shoe H, which rests upon the periphery es or tread of the wheel C. To the extreme end of the long portion of lever lll is attached the lower end of a vertical band-lever h2, which is provided with a handle h3.

In the construction of a car-truck a similar wheel C to that described is attached in a like manner to the car-beam on the opposite side of the ear, and the axle D journaled in the box prepared for it on the said axle, so that in the application ot' the wheel as constructed to cars requiring the service of springs the beam Awould in that case reprethe speed of sent the side beam of a car-truck, and the bearing of the platform in eithercase brought, as usual, upon the axle D. The track B is shown with side flanges and with corresponding side flanges to fit within the side Iianges of the track and aiiord safer transit of the car; but the construction of the flanges on the wheel and its track is immaterial, and may be the ordinary kind in use.

In the operation of the wheel reference is made to Fig. i5, which shows a curved-` line track, and in such tracks it is the ordinary custom to raise the outer track, which has the greatest length ot1 curve-rail, a slight distance, and the grade of the road-bed consequently is inclined in the direction of the shorter curve of the rail. The wheels C C are seen in Fig. G describing the curve, and in their rotation the axle D preserves in relation to the plane of the iioor of the car or the truck, as the case may be, the same position, the position of the axle in Fig. 2 showing, in illustration, simply the relation it bears to the wheel. In either direction in which the car is propelled, therefore, the small trailerwheels f13 are alternately an advanced 0r retreated guide to the wheel C. As the advanced wheel f 13 meets the curve of the track, it preserves between the sides of the extension flo fw of the radial arms on the wheel C an intermediate course to a point in which the retreated trailer-roller 13, following wheel C, also meets the curve in the track, in which position the tendency of the rollers f13 is to advance in a straight line or in the line of the chord described in relation to the curved rail between the advanced and retreated rollers f13 f, and to favor this result springs f 11 on the one relative inner side of the curves of the track-rail, which tend to keep the rollextend from ers at a point intermediate between the extensions flo f10 of the radial arm, are compressed and the roller moves laterally toward the relative side ot the extension flo which approaches the inner line of the curve in the track-rails.

It will be observed that the radial arms fA1 fl flf at their lower ends partake in union ot' a lateral sliding movement, and that the radial and vertical arm f is adjustable only and prevents too great a disparity in the angle of movement described laterally bythe lower portion f1 fw of the arms f4 The adj usting-screws ai dT are turned so as. to adjust the block a2, to which the upper end portions of the arms jb f" are pivoted, a distance in a lateral direction corresponding to that of the said portions flo flo, so far as to rectify the disparity between the width of the floor of the car and the track.

In the position described bythe radial arms f f* f5 the wheel C, in describing the curve in the track and in the momentum which it receives, hugs the outside track-rail. rlhe cylinder E slides outwardlyin the opening fo in circular plate as far as permitted toward the flange c, and in the rotation of the wheel past the radial arms f f" f5 the anti-friction balls c16 c1G prevent binding of the wheel C against the said arms, and the wheel C, being free to turn on the ball d, changes its angle as rapidly as the length ot chord between the rollers fw j increases and diminishes in describing the curve in the track. \7Vh en inequalities or obstructions are met with in or upon the track-rails, the extensions of the radial arms iirst give warning and turn on the pivots fs f8, the springs f1 are compressed, and the rollers passover the obstruction and meet the track beyond, thus guarding the wheel C from derailment. hen describing the curves in which the outer rail is elevated above the plane of the inner rail to preserve a vertical position of wheel C, the ball (Z shifts as the langle of the axle D is changed from a horizontal to an inclined position corresponding to the inclined groove of the track, the ball shitting its position within wheel C when the horizontal plane of the track is reached.
